SerialaNoi In the drawing the numeral 10 "fdesi'gnate's-'l an elongated rectangular greaseFcontanerforfbox which is preferably' square Y:in cros'sseetion; however, the box may be of any-'Suitable shape: Near its forward end the" box is supported by a short integral web or pedestal 11 extending upwardly from a base 12 integral therewith. The base has a somewhat pear-shape and has its forward end terminating short of the forward end of the box. Slots 13 are provided in the base for receiving bolts for fastening the base to 50` an elevator car or in any other place where the device is used. The base has a recess 14 for receiving a guide rail A, and this recess is considerably larger than the rail so as not to contact therewith, even though the base undergoes lateral Aand longitudinal movement. The forward end 'oflthebox'has afverticalcentral`slot 15 for re- ,o'eivirigf"theLA face andfsides of the rail A. f The slot?v fsuchareafas-to permit onlyv va slight clearance-'of 'the 'fside'si and "face lof theirail, therel'iyprevefnting afwastel-of grease between gther'dibaii'd lthe" edgeof -thegslotVAYA l f `Thefvertieal@fwalls'o' the b'oironeaoh4 side of :the slot 'arecurvecf twardl the slotv'to formguides 11176 'ffo'r :crowding thefgr'easeontothesides of the frail: when the grease? is'fed `forwardly. l The rforward edges or' llipsof Itheguides maybe reduced ii desired, butthisfis notvr essential.` Thefpox hasta-hinged lid 11i-'Tonr its topifprovi'ded with ears :lafor receiving `a thumb'boltlg hinged to one side of fthe' box. i This fasteningy prevents disf- 'plaicenie'ntI-ofthelid'hy the grease, when the :latterfisfedjforwardly.'l 1 fr' 'Y z j i'- AIffree slidableuprightfollowerf or plunger 20?'isfn'io'untedffn the'boX and 'is pivoted on its rearrside tofthe :forward end ofavcurved link 2,1.

-Ari*integral standard orvi post l24, preferably ush with the rear endof the boxextends upwardlytherefrom' and "has" a notchA` 25 in its upperend. The f'apexroffa sector shaped lever 26is'f'l1ingedvin the notch'on atraverse pintle 27 secured in "the'fstandardl The right Yangular legs :of Afthe' `lever eachfhav'e' ajweight` 28 sli'da'lzvle tliereon;` Each leg'vinayvhave a longitudinal slot 29 for? receiving a' transverse ,pin 30, Ycarried by the weight, whereby theweight islslidably confined onv said legg*y Each weight has-a set screw 3'1`for fastening it in position on its leg.

The lower leg of the lever 26 has an ear 32 near its outer end and the outer slotted end of the link 21 has a pivotal connection with this ear. It is obvious that when the lever is swung up and down the link 21 will slide the follower 20 backwardly and forwardly in the box 10. When the lever is in its extreme upper position, as is indicated in dotted lines in Figure 1, the lower weight 28 will be on one side of the pivot 27, While the other weight will be in a neutral Cil position above Said center; thus the lower weight will be exerting a downward thrust and having greater leverage than the upper weight, will overbalance said upper weight.

` When the grease stick B is first placed in the box the lever 26 will be swung to its upper position as is shown in dotted,` lines in Figure 1. The lower weight 28 will swing the lever downward,awhereby the link 21 will slide the follower 20 forwardly and force the grease stick B into contact with the rail A and the guides 16. This will require a short travel of the parts and thereafter, as the stick wears it will be advancedV by the downward swing of the lever. e

After the initial movement of the lever the upper weight 28 will be moved fromY its neutral position and begin to co-act with the lower weight in swinging the lever. It isohviousrthat these weights will complement each other asthe downward swing continues, thereby assuring a substantially uniform pressure throughout the swing.

By this arrangement the weights equalize. the

pressure and produce substantiallya uniform feed.- 1f two weights were not provided andonly a single weight were used, the force exerted to yfeed the grease, stick would vary in proportion to the leverage. Consequently, when the stick was almost consumed, as is shown .in Figure l. and `when it vwas first fed, it'would not be under as great pressure as it would bein ,intermediate vfeeding positions They two weights equalize the pressure andtend toessux'e a. uniform feed.V

e The operation and refillingl are very simple. By loosening the thumb bolt 19, swinging the lid 1'7 upwardly, and then lifting the lever 26, the follower. 20` Vis withdrawn andthe parts are ready to receive the grease stick;r All of this` may be done without theuse of tools, easily and quickly. After the grease stick is placed in the box the lever v,may bek released and the lid fastened.

No .further attention need be given the device' until the grease stick isworn out.y Y The description which has given' rocites more or less detail of a. particular embodiment of the invention which is set forth es new and useful. however, I desire it understood that the invention is not limited to such exact detailso! eOn-f struction, because it is manifest that and modifications maybe made within-the scope 0f the appended claims, without-departing im the spirit` of the invention. f v What I claim and desire tolsecure by Patent, is: A
